1. Changes and Pending Work

   This section must be removed before the draft progresses
   to RFC.


1.1.  Changes Since the Last Version

   Changes to get the MIB to compile.


1.2.  Pending Work

   No pending work items have been identified for this
      draft.


2. Introduction

   This memo defines a portion of the Management Information
   Base (MIB) for use with network management protocols in
   the Internet community.  In particular, it defines
   Textual Conventions used in IETF GMPLS and GMPLS-related
   MIBs.

Internet Draft                GMPLS TC MIB               January 2002




   This document suplements [TCMIB] that defines Textual
   Conventions and OBJECT-IDENTITIES for Multiprotocol Label
   Switching (MPLS) Management.  [TCMIB] may continue to be
   used without this MIB in networks that support only MPLS.

   Comments should be made directly to the CCAMP mailing
   list at ccamp@ops.ietf.org.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL",
   "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",
   "MAY", and "OPTIONAL" in this document are to be
   interpreted as described in RFC 2119, reference
   [RFC2119].

   For an introduction to the concepts of GMPLS, see
   [GMPLSArch].


3. The SNMP Management Framework

   The SNMP Management Framework presently consists of five
   major components:

   -  An overall architecture, described in RFC 2571
      [RFC2571].

   -  Mechanisms for describing and naming objects and
      events for the purpose of management.  The first
      version of this Structure of Management Information
      (SMI) is called SMIv1 and described in STD 16, RFC
      1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and STD 16,
      RFC 1215 [RFC1215].  The second version, called SMIv2,
      is described in STD 58, RFC 2578 [RFC2578], STD 58,
      RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].

   -  Message protocols for transferring management
      information.  The first version of the SNMP message
      protocol is called SNMPv1 and described in STD 15, RFC
      1157 [RFC1157].  A second version of the SNMP message
      protocol, which is not an Internet standards track
      protocol, is called SNMPv2c and described in RFC 1901
      [RFC1901] and RFC 1906 [RFC1906].  The third version
      of the message protocol is called SNMPv3 and described
      in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and RFC 2574
      [RFC2574].

   -  Protocol operations for accessing management
      information.  The first set of protocol operations and
      associated PDU formats is described in STD 15, RFC



Nadeau et al.                Expires July 2002               [Page 3]


Internet Draft                GMPLS TC MIB               January 2002



      1157 [RFC1157].  A second set of protocol operations
      and associated PDU formats is described in RFC 1905
      [RFC1905].

   -  A set of fundamental applications described in RFC
      2573 [RFC2573] and the view-based access control
      mechanism described in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP
   Management Framework can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information
   store, termed the Management Information Base or MIB.
   Objects in the MIB are defined using the mechanisms
   defined in the SMI.

   This memo specifies a MIB module that is compliant to the
   SMIv2.  A MIB conforming to the SMIv1 can be produced
   through the appropriate translations.  The resulting
   translated MIB must be semantically equivalent, except
   where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine
   readable information in SMIv2 will be converted into
   textual descriptions in SMIv1 during the translation
   process.  However, this loss of machine readable
   information is not considered to change the semantics of
   the MIB.

5. Security Considerations

   This memo defines textual conventions and object
   identities for use in GMPLS MIB modules.  Security issues
   for these MIB modules are addressed in the memos defining
   those modules.
